The short story is that I love the ACT cluster. On every major account including quality, price, management and fun, our cluster scores very high. We have a low number of users and they are all very smart. That makes clustering much more easy and fun.
The cluster provided by Advanced Clustering Technologies offered an excellent trade-off between cost and performance, together with competent technical assistance from the seller.
I've recommended ACT systems and tech support to a number of colleagues and have received nothing but thank-you's after purchase.
ACT is essentially unique in that they are very knowledgeable and "hands-on" with respect to their products and service...they truly enjoy rolling up their sleeves and solving technical problems!
Kyle and Paul provided outstanding service in getting our cluster on line. The training classes were detailed and made easy to understand which, as an educator, I found impressive. We can't wait to start running jobs on it.
